On the 2009-2015 Audi TTS 2.0 TFSI EA113 (CDMA), the Audi TTS Mk2 (2009-2015) with the EA113-based 2.0 TFSI (engine code CDMA) uses a high-pressure fuel pump (HPFP) driven directly by a dedicated lobe on the intake camshaft, with a cam follower (tappet) as the intermediary. The cam follower wears through its hardened surface over 30,000-50,000 miles, eventually allowing metal-to-metal contact between the HPFP and camshaft lobe. Once the camshaft lobe is worn, no amount of new cam followers will fix the issue; only a new camshaft ($2,000-$4,000) will restore fuel pump operation. If caught early, the cam follower is a $30 part that takes 30-60 minutes to replace. TTForum.co.uk and Audizine document this as a critical inspection item for EA113 2.0 TFSI engines. The TTS's higher boost pressure increases fuel pump cycling, accelerating follower wear. This follower design is specific to the belt-driven EA113 2.0 TFSI; it is not used on the chain-driven EA888 engines.

This issue also affects: Audi A3, Audi A4, Audi A5

Common Symptoms

Engine stumbling or surging under load
Loss of power during hard acceleration
Check engine light with fuel pressure codes (P2294, P0087)
Long cranking on startup
Engine stalling at idle
Ticking noise from fuel pump area (top of engine)

How to Fix

Every 20,000 miles, remove the HPFP (3 bolts) and inspect the cam follower surface. If the hardened coating is wearing through (visible copper/brass color), replace follower immediately ($30-$50 part, 30-60 minutes labor). Make sure the cam lobe is at its low point before reinstalling; if it is at its peak, you'll compress the spring and can break the mounting bolts. If the camshaft is worn (deep groove in the lobe), replace the camshaft ($2,000-$4,000). If the fuel pump has failed, replace the HPFP ($400-$800). To prevent this, inspect the cam follower every 20,000 miles as routine maintenance. Consider IE (Integrated Engineering) upgraded HPFP with roller follower to eliminate wear entirely.

Typical repair cost:$30 - $4,000
